Things go unnoticed at times. That's a fact.
We rush through a process and leave something out.
example: a single box serving of milk left on a counter instead of put back in the fridge.
I might see something out of place or find a misspelling in a book or magazine.
and then, there are good things that people do for others that go unnoticed.
There are consequences to our actions, either short term or long term.
